1990 Toyota Pickup 4 cyl Four Wheel Drive Manual
my truck kept popping EFI fuses so I check o2 sensor. When new engine was put in the mechanic never supported the wire going to the o2 sensor. Needless to say the exhaust melted the wire coating on all four wires to the o2. I have repaired the wires and so far no fuses have popped but the check engine light is still on. I unhooked the battery for 10 minutes and check engine light still on. The only thing I can thing that might be wrong in the carbon scoring in the wires from being in the exhaust. Maybe I didn't cut back far enough on the wire before reconnecting. Could this be it? A poor connection of the o2 wires?
